IMPROVEMENT IN PRESSES.

Specification forming part of Letters Patent No. 38,599, dated May 19,1863.

To all whom, it may concern..-

Be it known that we, ISRAEL PECK, of Southold, Suffolk county, New York,and WILLIAM H. H. GLovER, of the city, county 4 and State of New York,have invented certain new and usefullmprovements in Apparutus forPressing Oil from Fish, 85e.; and we do hereby declare and ascertain oursaid improvements, referring to the accompanying drawings, in which-Figure 1 is a general view of the machinery. Fig. 2 shows the details ofthe pressboxes; Fig. 3, the trough d, with table and press-boxesremoved.

Heretofore the process of pressing oil from fish has been to put thefish-scraps, after proper cooking, into cloth bags, and then submittingthem to hydraulic or other heavy pressure. This method was very slow andinvolved much expense in the manipulation in filling and discharging thebags, Src., and the scraps being pressed in large masses with no outletfor the oil, except around the edges between the followers of the press,the extraction of the oil was slow and imperfect. To remedy theseobjectionable defects has been the purpose of our improvements, thefirst novelty in which is to press the scraps in small quantities, and,secondly, to afford a free discharge of the oil from the press, and,lastly, to promptly discharge the scraps without manual labor.

The con struction of our apparatus is as follows, which may, however,vary in such details as are well-known and substantial equivalents: Ahorizontal table or conveyer, a, is pivoted on an axis at b, so as tofreely revolve. 1n proper recesses around the circumference of thistable a press-boxes c are put, the construction of which will be morefully described. Beneath the rotating table a there. is a trough, d,ofthe same curvature as the table. The sides of this trough extend up oneach side ofthe boxes c, above named. The trough is stationary and on apermanent foundation. It extends around about tw0-thirds of thecircumference of the table, (more or less,) but sucient to include theboxes that are llin g, intermediate ones that are draining, and thosethat are receiving the pressure, as hereinafter described. The bottom ofthe trough inclines to the point c, where the oil is discharged.

Within the two sides of the circular trough are ribs or ways r, standingup from the bottom of the trough, on which the bottom of the press-boxrests. Under the press these should be sufcient in number and strengthto sustain the pressure requisite to extract the oil from the scraps,but with spaces between them for the free discharge of the oil throughxperforations in the bottom of the box, which open into the spacesbetween the ribs r. The press-boxes c arebest made of metal, and consistof double sides all around, the inner one Vbeing strong enough to resistthe pressure and perforated with small holes, as clearly indicated inthe drawings. The outer case stands off a little from the inner one, isthinner and without perforations, serving simply to direct the oilthatis pressed through the holes in the inner case down into the troughd below. The bottoms of the boxes are pivoted near one end, as at p,Fig. 2, the joint being so constructed as to allow the bottom, when inplace, to move up and down a short distance, so as always to rest on theribs r of the trough without strain upon the joint.

The press followers may be worked so as to produce pressure by any ofthe mechanical devices-such as a toggle-joint, cam, or otherwise.

In the drawings we have shown a campress. It consists of one or morefollowers (two are represented in the drawings) lette] ed j'. Thesefollowers fareforced downwardinto the boxes c, which are brought underthem for the purpose. rlhe followers f are quickly raised, after thepressing is completed, by a spring or other proper device.

The operation is as follows: The number of boxes forming the set to bepressed at once are brought under the spouts, from which they arefilled, and the proper charge of scraps is dropped into them. They thenmove ou the distance sufficient to bring a second set under thefilling-spouts, where they stop long enough to allow the second set tobe iilled, while at the same time the first are draining into the troughcl below. /Vhen the second set is filled the boxes move on, so as tobring a third set under the iilling-spouts, while at the same instantthe first have arrived directly underthe press-followers f, and, whilethe third set are being iilled, the second drained,

the irst are receiving pressure, on the removal of which the table againturns so as to bring the next sets into the places of the rst. As thetrough d only extends aronnd in that direction far enough to receive theoil forced ont by the press, the bottoms of the boxes no longer restingon the ribs, before named, fall and discharge the scraps below. In thisthey are aided by striking a pin or bar in their descent at @which jarsout the contents. As the boxes come around again, just before they reachthe point Where they are to be filled, they strike a roller, k, at theother end ot' the trough d, and are raised into place. The movementofthe table and the boxes thereon is intermittent, corresponding withthe movementof the pressing-apparatus, to which it mayy be connected byany Weil-known mechanism that will effect the movement, and whichneednot be particularly specied.

It is essential that the follower should be thick enough to be above thetop of the box when driven home, to prevent the oil fromrunning over it,and this is a very important point in our constructon. The top edges ofthe box on the inside should be so notched as to allow any oil, &c.,that rises in it to flow over.

Having thus fully described our apparatus for pressing scraps, Sto.,what We claim, and desire to secure by Letters Patent, is-

l. The combination of rotating boxes, constructed substantially as andfor the purposes set forth, with a press and trough, as above specified.l

2. The employment of the boxes c, as above described, having a bottom.constructed and used as set forth, and with double sides, the interiorbeing perforated, all as herein made known.

In testimony whereof we have hereto set our hands.
